• Jquery and Ajax to Dynamically load IFrame

  - by JCHASE11

  I have a script that dynamically loads iframes inside a webpage. You can see the demo here: DEMO I want to use jquery to achieve the same rseult, but with a nice sliding effect. Basically, I have 10 links on a page. When the link is clicked, I want the iframe window to load in the new content and apply an effect to the transition. Does anyone know of any plugins that exist for this. I am not experienced enough to write a script from scratch, so any help would be much appreciated!

• How to execute statements in order in objective c

  - by Vu Tu?n Anh

  When i tap on my button, my function was called [myBtn addTarget:self action:@selector(myFunction) forControlEvents:UIControlEventTouchUpInside]; In my function, a collection of complex statement will be executed and take a litte bit time to run, so i want to show Loading (UIActivityIndicatorView) as the following: -(void) addTradeAction { //Show Loading [SharedAppDelegate showLoading]; //disable user interaction self.view.userInteractionEnabled = NO; //execute call webservice in here - may be take 10s //Hide Loading [ShareAppDelegate hideLoading]; } When tap on myBtn (my Button) - after 3s or 4s, [ShareAppDelegate showLoading] was called. It is unusual when i use [ShareAppDelegate showLoading] on other Function, - it work very nice, i mean all the statement be executed in order. All i want, when i tap on My Button, Loading will be called immediatelly. Tks in advance

• gametutorials.com questions and reviews DirectX tutorials

  - by numerical25

  Just curious to know if anyone has ever used gametutorials.com products for learning directX. I was debating on whether I should buy it or not. I read online that most of his tutorials were written in the source code. It's nice to heavily comment your code but if most of the tutorial is in his code then I don't think that is necessarily the best way to do a tutorial. But anyhow, I am not sure about that, I am just checking for clarification. and checking to see if it would be a good investment.

• Does Displaytag stash the "media type" in a page or request attribute?

  - by Pointy

  When you enable "export" from Displaytag, the tag code gives you links with special magic parameters that the tag recognizes as indicators that the table contents should be exported (as CSV, Excel, whatever). Well I'm interested in detecting the media type so that (for example) I can exclude columns that make no sense in an export (embedded action buttons, for one thing, or checkboxes for row selection). I suppose I could write a table decorator and use that to stick the media type on the request, but it'd be nice to avoid that if the tag already does it. The documentation is not clear on the subject; I guess I can start digging through the source code too.

• ORM framework that extends base class with database-implementation.

  - by aioobe

  I have a game consisting of a client / server + a webpage. A central notion in both client and game-/webserver is an Account. Accounts are stored in a database thus I'm in need of some ORM and recently had a look at Hibernate and Cayenne. My understanding however, is that both frameworks provide an "DatabaseBackedAccount"-class which I extend with my other Account methods. My problem is that the Account class is reused heavily on the client side, and I would obviously not want to include database-related code on the client implementation. My current solution is to have an Account class (shared by server and client) and extend this with a DatabaseBackedAccount (overriding setter-methods and providing a commit method) on the server side. I find this quite natural and nice, however I've had to implement all gory sql-details and ORM myself. Is there any way to "turn the table" in any existing ORM framework, so that the generated classes extend my existing class?

• Scaffold default files are the best practice?

  - by antpaw

  Hey, i have some experience with MVC. but I'm new to rails. I'm using the scaffold command to generate some default files. The model looks clean and nice, but the controller and the views aren't really dry. The contents of new.html.erb and edit.html.erb are almost the same and the methods new/edit and create/update are doing almost the same thing. In other frameworks i've used only one view for updating and creating new entries and also the same method in my controller by setting the id as an optional parameter. Do they use this structure to keep things RESTful (i have not much of a clue about rest :()? Is it the best practice to use this default stuff for crud?

• How to get width of a div in pixels using JQuery (IE)

  - by Casidiablo

  Hello there. At first glance it sounds easy... when using JQuery one can use the .width() method to retrieve the width of an element. The problem comes when the DIV element does not have its size in pixels but in words like 'auto' or 'inherit'. When I do this it works nice in Firefox and Chrome even if the size is specified in words: alert($('#id_div').css('width')); // these two sentences does not It returns something like: 96px. But, IE returns the word 'auto'. I need to know the size it has in pixels because I have to do some calculations with that number... so, I've been wondering how to solve this problem. How can I solve this issue? Thanks for reading.

• Open source configuration framework for ASP.NET - does one exist?

  - by Jon

  We currently have an old product written in classic asp and are about to re-write parts in ASP.NET. One big problem is that much of the cutomer-specifics within the system are hard coded. We want to split this out for specific customers by storing data in the database. Is there a quick an easy open source framework which allows me to set up some quick tables and simple UIs to allow me to change configuration items? We have 6-7 modules, and it would be nice to have the ability to have system admins gain access to a configuration area where they can set-up settings in a tabbed UI format, settings could also be set-up to allow dropdown, fields, numbers etc. The items could then be accessed via classes in C#/vb for use within the operational parts of the system. If not, I'm suprised and it might even be a good basis for a new open source project.

• MySQL, how can I SELECT WHERE one field value doesn't occurs in another?

  - by Jules

  I'm trying to do a search on my test server, speed isn't so important. I want to find if a phrase, the whole contents of one field, occurs in any part (as a whole) doesn't occur in another field. Heres my current query which finds if the phrase does occur SELECT pads.padid, pads.programname, keywords.word FROM Pads JOIN keywords ON Pads.Padid = keywords.Padid WHERE pads.Programname = keywords.word AND RemoveMeDate = '2001-01-01 00:00:00' My problem is that the field word contains other words too. I need to produce a count of where there isn't a keywords record with keywords.word equal to pads.programname ? EDIT: So if I have these records Pads: PadID=3 ProgramName=my prog PadID=4 ProgramName=Bad prog PadID=5 ProgramName=Good prog PadID=6 ProgramName=other prog Keywords: PadID=3 word=fox prog PadID=3 word=pig prog PadID=4 word=big prog PadID=4 word=nice prog PadID=5 word=fox prog PadID=6 word=bad prog PadID=6 word=fox prog The query I want would retun a count of 3 and record 6 has bad prog

• Semantic stuff (RDF, OWL) on mobile phones - is it possible?

  - by Brian Schimmel

  I'm thinking about using semantic (web) technogies like RDF and OWL in an application on mobile devices. Currently I'm targeting android, but I'd also be interested in the possibilities on the iPhone and on J2ME. I would like to use a lib instead of implementing everything from scratch. I know that there are some libraries and frameworks like Jena, Redland, Protégé but they don't state on which platforms they are known to work. Having a dynamic object model and parsing from and to XML are must-haves for me. I'd also like to use reasoning, but I've been told it was rather computing-intensive, so that's only a nice-to-have. For all platforms mentioned, the question can be interpreted as Is it possible in theory (especially for J2ME I'm not sure) Are there libs that are known to work on those platforms? Is the performance on a mobile platform good enough for real world usage?

• Changing <img src="XXX" />, js event when new image has finished loading?

  - by carillonator

  I have a photo gallery web page where a single <img src="XXX" /> element's src is changed (on a click) with javascript to show the next image—a poor man's ajax I guess. Works great on faster connections when the new image appears almost immediately. Even if it takes a few seconds to load, every browser I've tested it on keeps the old image in place until the new one is completely loaded. It's a little confusing waiting those few seconds on a slow connection, though, and I'm wondering if there's some javascript event that fires when the new image is done loading, allowing me to put a little working... animated gif or something up in the meantime. I know I could use AJAX for real (I'm using jQuery already), but this is such a nice and simple solution. Besides this lag, is there any other reason I should stay away from this approach to changing images? thanks.

• How do I truncate a .NET string?

  - by Steve Guidi

  I apologize for such a question that likely has a trivial solution, but I strangely could not find a concise API for this problem. Essentially, I would like to truncate a string such that it its length is not longer than a given value. I am writing to a database table and want to ensure that the values I write meet the constraint of the column's datatype. For instance, it would be nice if I could write the following: string NormalizeLength(string value, int maxLength) { return value.Substring(0, maxLength); } Unfortunately, this raises an exception because maxLength exceeds the string boundaries. Of course, I could write a function like the following, but I was hoping that something like this already exists. string NormalizeLength(string value, int maxLength) { return value.Length <= maxLength ? value : value.Substring(0, maxLength); } Where is the elusive API that performs this task? Is there one?

• What's the point of lambda in scheme?

  - by incrediman

  I am learning scheme. I know how to use both lambda and let expressions. However I'm struggling to figure out what the point is of using lambda. Can't you do everything with let that you can with lambda? It would be especially helpful to see an example of a situation where a lambda expression is a better choice than let. One other thing - are there also situations where let is more useful than lambda? If so such an example would be nice as well. Thanks!

• How to pass parameters to report model in Reporting Services

  - by savras

  I'm developing report in RS that show top N customers based on some criteria. It also allows to select number of customers and period of time. Is it possible to do it by using report model? Thing that it seems to be difficult is how to pass parameters determined by user. Another thing that in my oppinion is very disappointing is that i cannot use SQL query as dataset query, because it uses odd and elaborate XML. Although report model items seem to map its fields to query or table fields. I m concerning using report models because i need to provide uniform data model (the same tables and fields) for more or less different database schemas. It would be very nice if somebody would explain what can be done with report models and what can not.

• Is there a FSRef in iPhone SDK or is there something that can be FSRef's alternative?

  - by unknownthreat

  The question may sound stupid, but the thing is this: I am learning how to use a Audio Queue, and the example I've taken (aqtest) has been a nice guide for me until I recently found out that aqtest is not for iPhone. (stupid me) I served around the Internet and found out that there is no FSRef for iPhone. If possible, I want to find a way to work around FSRef thinggie. So here comes the question: can I use something else instead of FSRef that exists on the iPhone SDK? Or am I missing something?

• 3G/Edge/GPRS IP addresses and geocoding

  - by LookitsPuck

  Hey all! So, we're looking to develop a mobile website. On this mobile website, we'd like to automatically populate a user's location (with proper fallback) based on their IP address. I'm aware of geocoding a location based on IP address (mapping to latitude, longitude and then getting the location with that information). However, I'm curious how accurate this information is? Are mobile devices assigned IP's when they utilize 3G, EDGE, and GPRS connections? I think so. If that is so, does it map to a relatively accurate location? It doesn't have to be spot on, but relatively accurate would be nice. Thanks! -Steve

• Java variables -> replace? RAM optimization

  - by poeschlorn

  Hi guys, I just wanted to know what happens behind my program when I declare and initialize a variable and later initialize it again with other values, e.g. an ArrayList or something similar. What happens in my RAM, when I say e.g. this: ArrayList<String> al = new ArrayList<String>(); ...add values, work with it and so on.... al = new ArrayList<String>(); So is my first ArrayList held in RAM or will the second ArrayList be stored on the same position where the first one has been before? Or will it just change the reference of "al"? If it is not replaced...is there a way to manually free the RAM which was occupied by the first arraylist? (without waiting for the garbage collector) Would it help to set it first =null? Nice greetings, poeschlorn

• Metadata requirements for developers

  - by Paul James

  I'm tasked with providing a list of metadata requirements our data warehouse developers might need. This is not the business metadata (nice descriptions etc), but rather data required for change management (also known as impact assesment), data lineage etc. I've seen this article Meta Meta Data Data - Ralph Kimball but as I'm not the first person to do this I'm throwing it to the SO community. The actual question is this: What metadata do datawarehouse developers require to design, develop and manage change in ETL routines? PS: I'm trying to keep the answer platform agnostic but for context this is an Oracle database with PL/SQL and Datastage.

• How to determine which side of a 3D plane is showing?

  - by Josh Santangelo

  This is a 3d n00b question. I'm working on a WPF control which implements the basics of Silverlight's PerspectiveTransform feature, allowing a 2D plane to be rotated on any of the three axes. It works pretty well. However I'm a little stuck on the math required to determine whether or not the back of the plane is showing. My naive code for figuring that out now is: bool isBackShowing = Math.Abs(RotationX) > 90 && Math.Abs(RotationY) < 90; if (!isBackShowing) { isBackShowing = Math.Abs(RotationX) < 90 && Math.Abs(RotationY) > 90; } However, this fails when the rotation is between +-270 and +-360 on either axis. The underlying transform is using a Quaternion object to do the actual rotation, and that has nice Axis and Angle properties, so I'm guessing I could just use that if I knew how.

• [C#] How to consume web service adheres to the Event-based Asynchronous Pattern?

  - by codemonkie

  I am following the example from http://msdn.microsoft.com/en-us/library/8wy069k1.aspx to consume a web service implemented (by 3rd party) using the Event-based Asynchronous Pattern. However, my program needs to do multiple calls to the DoStuffAsync() hence will get back as many DoStuffCompleted. I chose the overload which takes an extra parameter - Object userState to distinguish them. My first question is: Is it valid to cast a GUID to Object as below, where GUID is used to generate unique taskID? Object userState = Guid.NewGuid(); Secondly, do I need to spawn off a new thread for each DoStuffAsync() call, since I am calling it multiple times? Also, would be nice to have some online examples or tutorials on this subject. (I've been googling for it the whole day and didn't get much back) Many thanks

• How can I simply "run" lisp files

  - by Annan

  Python When I learned Python I installed it on windows with a nice gui installer and all .py files would automatically run in python, from the command line or explorer. I found this very intuitive and easy, because I could instantly make plain text files and run them. Lisp I'm starting to learn lisp and have decided (from reviews) that SBCL is not a bad lisp implementation. Is there a way to setup SBCL to run .lisp files as easily as with Python? Are there other lisp implementations that have this?

• Ajax Fancy Capture in CakPHP

  - by Constantin.FF

  I have found a nice ajax capture which i would like to use in a CakePHP framework website. The plugin can be found here: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin What I have tried: in the controller: public function index($slug = null, $capture = false) { if($capture AND $capture =="get_capture"){ $rand = rand(0,4); $_SESSION['captcha'] = $rand; echo $rand; die; } if (!empty($this->data) && $_POST['captcha'] == $_SESSION['captcha']) { .... save the post } } in the view: $selectURL = " $(function() { $('.ajax-fc-container').captcha({ borderColor: 'silver', captchaDir: 'http://localhost/img/capture', url: 'http://localhost/contacts/index/contacts/get_capture', formId: 'MessageIndexForm', }); });"; $this->Html->scriptBlock($selectURL, array('inline' => false)); also I have tried with url: 'http://localhost/js/capture.php' which is the original file coming with the plugin but still not working.

• ACCESS 2003 Excel 2003 : VBA for opening Excel file from Access and copying a pictre from excel the

  - by Justin

  So I have an excel workbook that has a nice global map of shaperange objects. With some very simple code I can change the colors, group and ungroup collections of countries into arrays, etc...and it works pretty well. However, I would like to bring this into Access. So I could copy and paste all the shapes into an access form manually, but then they become pictures and I cannot change the colors of the countries (shaperange objects) to have the map act interactively as I can in excel. So I am thinking that I know how to use excel functions from access, and how to open excel from access. Is there a way to copy an object from excel (I know the file name and the shape name that i mean to copy everytime), and bringing it back to access to paste on a form? Atypical, I know, all my Access questions are. Thanks!

• What is viewstate in JSF, and how is it used?

  - by MatthieuF

  In JSF, there is a viewstate associated with each page, which is passed back and forth with submits etc. I know that viewstate is calculated using the states of the various controls on the page, and that you can store it either client side or server side. The question is: how is this value used? Is it used to validate the values sent at submit, to ensure that the same request is not sent twice? Also, how is it calculated - I realise that richfaces may be calculated differently from myfaces, but an idea would be nice. Thanks.
